Ct scan abd/pelvis, can it be melanoma (had melanoma), what should be done? Mild-low attenuation/left arnexal region likely related to ovarian cyst.

Ct scan abd/pelvis, can it be melanoma (had melanoma), what should be done? Mild-low attenuation/left arnexal region likely related to ovarian cyst.

An ultrasound: Would confirm that this simply represents an ovarian cyst. The chance of the finding you describe representing melanoma is almost zero.

Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more

Can epidural fat attenuation be from cushings syndrome?

Can epidural fat attenuation be from cushings syndrome?

Yes: Patients with elevated steroid levels are predisposed to epidural lipomatosis, which can cause spinal stenosis.

Bilateral subcentimeter low attenuation lesions in kidneys?

Bilateral subcentimeter low attenuation lesions in kidneys?

Cysts: That typically represents cysts. Bilateral cystic disease can be either a normal variant if a small number and age of the patient, or polycystic kidney disease.

Lab results: You need to ask the physician who ordered the test to explain the findings to you

Fibre length, overall signal attenuation for an optical link, coupling loss exam, what are these?

Fibre length, overall signal attenuation for an optical link, coupling loss exam, what are these?

Non-medical: These are terms out of fiber optic technology relating to the signal loss related to length of the fiber, loss jumping the gap between two fibers juxtaposed and loss from characteristics of the optical fiber.

SPECT anterior defect - breast attenuation, What?

SPECT anterior defect - breast attenuation, What?

An overlapping: Breast can cause an artifact on a normal SPECT that causes a cardiac defect on the scan. The photons are absorbed, or attenuated, by the breast tissue. There is no real abnormality. If that is what it is, the scan is essentially normal.

What can be done for attenuation on my left kidney?

What can be done for attenuation on my left kidney?

Not clear by birth?: Attenuation is a sonographic term. Need more information before telling opinion. Infections can cause attenuation, poorly formed kidney can cause attenuation, some kind of cysts/masses can cause. Need to know whether it is uniform of attenuation of whole kidney or a part of the kidney alone.

What is the cause of low attenuation lesion in your kidney?

What is the cause of low attenuation lesion in your kidney?

Several causes: Can be a cyst or several possibilities; best to check with your doctor or see a nephrologist.

What's moderate liver infiltration with large attenuation? Serious? Thanks

What's moderate liver infiltration with large attenuation? Serious? Thanks

We need more info: Give us the history of what you had done (? which test and why???). Perhaps it is fatty infiltration of the liver. This is a condition that develops in over-weight individuals who are sedentary. You need to eat less and exercise more and lose some weight or tell us more if it is some other condition

"Incidental low attenuation lesion" found in kidney. 7mm in size. What does "low attenuation" mean?

"Incidental low attenuation lesion" found in kidney. 7mm in size. What does "low attenuation" mean?

Low attenuation: Means it absorbs less xrays. Usually this means that it is something less dense than adjacent tissue. For example, a fluid filled structure (such as a cyst) has lower attenuation than a solid mass. In the kidney, an incidental low attenuation lesion usually indicates a benign cyst. This can be confirmed with an ultrasound.

What is parenchyma is hyperechoic with increased attenuation of beam and is homogenous in liver?

What is parenchyma is hyperechoic with increased attenuation of beam and is homogenous in liver?

See answer: While it is difficult to interpret a comment from the report, especially without seeing the images and the relationships and appearance of the other hepatic structures (vessels, bile ducts) this may indicate diffuse fatty infiltration – which could be metabolic or the result of drug treatment. Discuss with your clinical dr.

Could male taking clomiphene for years have attenuation of endogenous LH production from pituitary?

Could male taking clomiphene for years have attenuation of endogenous LH production from pituitary?

Probably not: Clomiphene works by blocking estrogen at the pituitary. The pituitary sees less estrogen, and makes more lh. More LH means that the leydig cells in the testis make more testosterone. I don't see how Clomid (clomiphene) would cause the LH production to attenuate.

There is a medium-sized inferoseptal and a small sized apical defect worse at rest suggestive of soft tissue attenuation and reconstruction artifact.

There is a medium-sized inferoseptal and a small sized apical defect worse at rest suggestive of soft tissue attenuation and reconstruction artifact.

Scan: I assume This is a nuclear cardiac stress test and if so, is consistent with scarred heart muscle possibly related to coronary artery blockages and old damage. I presume that your EKG was also abnormal. These important findings are best evaluated by a cardiologist skilled in interpreting nuclear cardiac scans, and who knows all your findings. Coronary Angiography may be recommended.

What does - liver- low attenuation lesions too numerous to count. Lesions throughout the liver nonenhancing. Statistically represent small cyst versu?

What does - liver- low attenuation lesions too numerous to count. Lesions throughout the liver nonenhancing. Statistically represent small cyst versu?

Haemangioma/metastas: Blood vessel malformations can present in liver. Metastasis of cancer can occur. Certain parasites can form cysts in liver. Hematogenous spread of infection can seed in liver. See PMD for correlation.

What does "Subtle increased attenuation in the rightperihilar region" relative to a chest x-ray mean?

What does "Subtle increased attenuation in the rightperihilar region" relative to a chest x-ray mean?

Shade o'Gray. Use...: HT Prime. The perihilar region is the part of the lung where the airways & arteries enter. "Increased attenuation" means that the picture (actually, the negative) is brighter. That could be from the presence of inflammatory fluid or infection or congestion, but most often means that the Radiologist ought to check his glasses or equipment. Without symptoms, it's a meaningless (but costly) finding.

Diffuse mild low attenuation hepatic steatosis Several sub centimeter lesions is the something to worry about?

Diffuse mild low attenuation hepatic steatosis Several sub centimeter lesions is the something to worry about?

Liver lesions: Fatty liver and liver lesions concerning. I would suggest further testing with CT or MRI and if need see liver specialist.

What does 'prominent soft tissue density demonstrating decreased attenuation on postcontrast imaging' mean on a CT report?

What does 'prominent soft tissue density demonstrating decreased attenuation on postcontrast imaging' mean on a CT report?

Depends...: Depends on where in the body it is what structure it is referring to - like a lymph node, in an organ, outside an organ or lymph node region, or in the subcutaneous tissues. I would need more information to expand more.

I had a m. malleolus fx 18mo ago from being ran over by a truck, now have talar lesion, del lig attenuation, PTT. Would MRI have dx at initial ORIF?

Possibly, if it was-: -injured with the crush to your ankle, it may show bone edema, it you have avascular necrosis, it would not as it is due to the loss of blood supply, and imaging changes take time. To the eye @ your surgery, it would not be visualized, but if it were it would look normal.
